Earthquakes are vibrations of earth caused by the rapid release of energy. These earthquakes can be caused by faults in the Earth’s crust scraping against each other. Faults are constantly sliding past each other‚ but can occasionally have difficulty when the earth around these faults cracks‚ causing the path to become rugged. When they don’t slide easily‚ they cause tension. When the tension and pressure is released‚ this causes said vibrations that can be large enough to damage and destroy cities
